IIROC published guidance on February 1 on specific questions respecting "locked" and "crossed" markets in the context of NI 23-101 Trading Rules and its companion policy. The guidance reflects the repeal of the "best price" obligation and the other consequential amendments to UMIR discussed in our post of earlier today. IIROC published a proposed version of the guidance in April 2010 and yesterday's notice also provides responses to comments it received on its original proposals.
For more information, see IIROC Notice 11-0042 and IIROC Notice 11-0043.
